According to SBI the reason behind the postponement of its exchange launch date is basically for security improvement purposes which they also apologized for.

“We made a decision which will take some extra time to further strengthen security measures, assets management, and customer management systems in order to make sure cryptocurrency exchange users are most secured,” SBI wrote in the announcement.

SBI Group plans to launch cryptocurrency exchange SBI Virtual Currencies was first made public in October, 2016.

SBI’s move to boost the exchange’s security system is likely in part motivated by the massive $534 mln hack of one of the largest Japanese cryptocurrency exchanges Coincheck on Jan. 26. “The biggest theft in the history of the world” forced Japan’s Financial Services Agency (FSA) to increase the scrutiny of cryptocurrency exchanges, with particular attention to computer system safety measures and the management of customers assets.
